DE3017408A1 - Fruit machine with three drums - has sensing stage coupled to drums with counting stage for bonus games - Google Patents

Abstract

The fruit machine includes a facility for a series of bonus game possibility. The three rotating drums are driven until the control of signals generated from a main controller. A sensing unit contains an array of switching stages that are tripped to indicate winning combinations. The outputs from the sensing unit are fed to the win counter that contains a stage (10a) handling the normal wins and one handling the bonus wins. The input signals are converted by a parallel to serial converter that provides an equivalent number of pulses for a counter. Wins in the range 2 to 20 cause a relay to be tripped to eliminate the middle drum.

Description

Slot machine with several circulating units

The invention relates to a slot machine with several winning symbols bearing circulating bodies, which are controlled by a central control device via individual Control lines each set in circulation by a running signal at the start of the game and at irregular times due to the fall of the respective run signal for Be brought to a standstill, which are coupled with one at the end of the game from the control center Control device activatable profit scanning device for determining normal and special game wins, with a winning key with opposite in special games the normal game of increased expectation of winnings is applied, with a credit counter for normal and special game winnings, the one with the Gewinrlabtasteinrichtung line manifold formed from individual lines.

Slot machines of the type mentioned are in various Embodiments can be found in restaurants and amusement arcades. They mostly own three recirculating bodies, which can be cylindrical or disc-shaped. on On the surface that can be seen from outside through windows, the circulating units have winning symbols. The circulating bodies are shut down one after the other; after all recirculating bodies to the If you have come to a standstill, the combination of symbols decides whether you win or lose. Ge] d and special game winnings are promised in different amounts; with the latter there is a winning key compared to the normal game increased Chance of winning to apply.

Special game prizes, so-called series, enjoy due to the high profit expectation great siftiness; the more often special game hits can be achieved are, the greater the gaming incentive exercised by the machine. Newer machines have therefore been set up in such a way that it is more likely that series can be achieved are, however, the length of the series in favor of an economically justifiable Profit distribution is kept short. In a short one, for example two special games comprehensive series, there is often no profit with the result that the player is out Disappointment the game stops.

The invention is based on the object of a gambling machine of the type mentioned at the beginning, the short series compared to a long one Series granted increased chance of winning.

The object is achieved in that at least one of the control lines a circuit breaker controlled by gain signals that can be derived from the line manifold This allows recirculating units, in whose control line the disconnector is enclosed after taking one of the special game winners' positions a predefinable level of the credit counter - if a special game is running - in the profitable position will be held, with a decreased number again Umlaur bodies starting up and stopping in unpredictable positions Preference is given to the signals that the circuit breaker Bring into its separating position, special game profit lines assigned from a low profit amount of the head of department.

An advantageous embodiment of the invention can be the dependent claim can be removed.

An Ausführungsbeispie the invention is shown in the drawing and explained in the description below.

The only figure shows azoles necessary for understanding the invention Parts of a cash machine.

Regularly at the beginning of the game, a central unit marked 1 is generated Control device running signals that are transmitted via individual control lines 2, 2 'and 2' ' to not shown electromechanical'Organen three recirculating bodies 3, 4 and 5 are directed. The revolving bodies 3 to 5 each run as long as the individual one Running signal is pending. The central S control device 1 sends the run signals one after the other end at illegal times, so that the recirculating bodies 3 to 5 at the end of the game stand in unpredictable locking positions.

The recirculating bodies influence the position they have taken 3 to 5 switches, e.g. s6, sounds6 "of a profit sampler 6, which regularly at the end of the game via a control line 7 from the central control device 1 can be activated. The profit sensing device 6 is on the respective profit level related outputs 8 and 8 'for normal and special game wins, respectively 10-connected to a credit counter via a line manifold 9 and 9 '.

The credit counter 10 contains a section 10a for counting normal items and a section 10b for counting special games; the former is not shown in more detail, since it is not the subject of the invention.

The section 10b contains a parallel-to-serial converter 11.

When the activated profit scanner 6 has a profit of, for example has recognized fifty special games, then it says on the line marked "50" an H signal that the parallel-serial converter 11 after its activation on the part the central control device 1 causes fifty pulses at its output 12 deliver the 'through a NUND element 13 to a first counter 14 in its status Fifty raise. If this was previously at zero, its zero position 15 was occupied; now it's his fifty place. The output of the zero point 14 has an input an inverting AND gate 16 connected so that its with the profit sampling device 6 connected output is energized when the counter reading deviates from zero. The occurrence of the excitation switches a profit evaluation logic (not shown) in the profit sensing device 6 from normal game to special game; with the latter a winning final with a higher profit expectation applies.

In the following it is assumed that after normal games a special game win comes up, which includes ten games, after which on a line labeled "10" of the line manifold 9 'an H signal occurs.

Those designated for the lower special game win amounts and from "2" to "20" Lines of the line manifold 9 'are also each provided with an input of an OR element 17 connected> whose output is connected to the set input S of a flip-flop 18 is, so that this is now set, whereby its Q output is signal-carrying.

The signal from the Q output blocks the NUND gate 13 and prepares AND gate 19 before, ten pulses from the Paral.3el.-series converter 11 to a second To switch through special game counter 20, the status of which is increased from zero to ten.

Previously, its zero position 21 was occupied, the output of which was a second Input of the inverting AND gate 16 is connected, so that this on both Inputs from Nujl positions 15 and 21 of both counters 14 and 20 received a signal, which means that its output is low, with the profit evaluation logic (not shown) worked in the profit scanner 6 in normal game mode.

The Q output of flip-flop 18 is also connected to the inverting input of a NUND member 13 'and with that not inverting input an AND gate 19 ', the outputs of which each have a decrement input 22 and 23 of the counters 14 and 20 are connected. Received at their second entrances the members 13 'and 19' regularly in each game via line 24 a game deduction signal from the central control device 1, which decreases the reading of the second counter 20, as long as the flip-flop 17 is set.

When the level of the second special game counter 20 decreases to zero is, then the output of the zero point 21 carries a signal that is also in the reset input R of the flip-flop 18 is passed, whereupon the signal at the output Q drops.

The following game deduction signals then pass through the NUND element 13 'to the reading of the first special game counter 14, which may alternate from zero to decrease.

The control input is also connected to the Q output of the flip-flop 18 a controllable disconnector 25, which is in the control line 2 'for the second tJmlaufkörper 4 is inserted, and the running signals from the in its rest position central control device 1 switches through. When the flip-flop 18 is set, the isolating switch 25 assumes its working position, with the effect that the 7 expands Recirculating body 4 remains in its profitable locking position in the next game. Thus, due to the reduced number of restarting and Bodies coming to a standstill in unpredictable resting positions a higher chance of winning a special game is granted until the second special game counter 20 comes to its zero position.
